The CPU has two main parts:
-The Control Unit
It is responsible to direct the system to execute instructions. It helps in communication between the memory and the arithmetic logic unit.
-The Arithmetic and Logic Unit (ALU)
The ALU is responsible for performing all logical and arithmetic operations like the comparison between numbers or adding numbers.

An arithmetic-logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It is the basic building block of a computer's central processing unit (CPU). Modern processors contain very powerful and complex ALUs. In addition to the ALU, modern processors contain a CPU.

What is the difference between ALU and CU?
ALU- Arithmetic Logic Unit CU- Control Unit alu performs the arithmetic and logic operations. cu is the one which controls the entire processing.
The alu and cu jointly known as?
CPU
What hold counters data instructions and addresses that the ALU is currently processing?
Registers
What is a register in microcontroller?
Registers are small memory elements of size in few byte or word. Registers can be accessed quickly by the ALU (Arithmetic and Logic Unit) of micro controllers.
What are the components of the processor?
ControlUnit / ALU / Registers Control Unit / Arithmetic and logic unit / Registers A processor as the name implies process functions and data. It consist of three major components of function. I/O input /output , ALU mathematic logic unit, and finally the control unit.
Which unit of computer performs arithmetic and logical functions?
The ALU (arithmetic logic unit) An ALU loads data from input registres, an external Control Unit then tells the ALU what operation to perform on that data, and then the ALU stores its result into an output register. Other mechanisms move data between these registers and memory.
What are the 3 units in a computer?
the arithmetic logic unit (ALU), which performs arithmetic and logical operations, and the control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
What is CPU and write the function of its two main componentsie alu and cu?
write the function of cpu
What are the two primary sections located on the CPU?
the units of the CPU are :- ALU (arithmetic and logical unit) CU(control unit) the ALU handles the arthmetic operations being done by the application and the CU is responsible for handling the instruction passed by the micro processor.
What does ALU use to hold data that is being processed?
It doesn't. Usually, the CPU general purpose registers provide input to the ALU, and the Accumulator receives the answer temporarily until it can be placed back into one of those registers. Exactly how this is wired up varies widely with different CPU architectures, but in the theoretical model of an ALU, you specify which function you want, and the answer appears at the output as fast as the gates can operate. It is up to the CPU to store it somewhere.
Where registers are located?
A register is a storage location within the CPU as part of Datapath. CPU consists of datapath and control unit. Datapath comprises of register file (which consists registers and logic ) ,ALU and memory.
Differentiate between CU and ALU?
The ALU (Arithmetic-Logic Unit) is generally a subsection of the CPU (Central Processing Unit). While the CPU is the master driver of a computer, the ALU is a processing area optimized to handle mathematical computations and logic comparisons. The processor controller passes operation codes and operands to the ALU, which performs the requested operation on the supplied data and passes back the results.
